Maxum 4600 SCB fuel burn with Cummins 370HP

[Beefmaster]

I am considering purchasing a 4600 SCB with the Cummins 370HP engines. Can someone give me some realistic burn rates and speed at various RPMs? I found some info on the 450's and the fuel economy looks pretty good but can't find much on the 370's. Thanks in advance.

Thanks dbriceno. It looked like the charts for the 4600 were theoretical data from Cummins. I am hoping to get some actual info. The owner of the boat I am interested in did not have a real good idea of his burn rate. Trying to see what the optimum speed/economy I can expect. I would like to know what to expect cruising around 8-10 mph and what to expect if I get it on plane and backing it down a bit.

Did you happen to see this graph? It's listed as an actual rate.

I've never worried about burn rate, I would concentrate more on general performance like do the engines make WOT and at what RPM does it plane. The burn rate is what it is...

Frenchie - That is exactly what I was looking for. Thank you for pointing that out to me.
